NEEDLE-FRAME F OR SPlNNlNG-MACHINES- SPECIFICATION forming part of Letters Patent No. 733,608, dated July 14, 1903.

Application filed July 14, 1900.

To all whom it may concern:

Be it known that I, GUSTAVE VAN MEURs, engineer, a citizen of Belgium, residing at 410 Ohaussee de Tcrmonde, Ghent, in the Kingdom of Belgium, have invented certain new and useful Improvements in l eedle-Frames for Spinning-Machines, of which the following is a clear description.

This invention relates to an arrangement for the continuous spinning of wool and cotton (untwisted wefts, warps, twistings) and other textile materials; and it consists in a frame or box with a needle having an alternating vertical movement, the needle being straight and poised or balanced in relation to the thread which runs below it and rounded off at its ends and being capable of turning freely around a spindle with a rotary motion for effecting the twisting and winding under tension on the said spindle of the thread produced by the roving coming from suitable cylinders.

By referring to Figures 1, 2, and 3 it will be seen thatthe needle-box consists substantially of abase or bottom 1 and a cover 2, both fur nished with a central opening 3, through which the spindle 4: runs. The needle 5 is lodged in a space reserved for the purpose between the bottom and the cover and can turn and move freely on the upper surface of the bottom 1 around the spindle 4.

In examining Fig. 1 it will be observed that the roving 9 coming from the bobbin passes between the cylinders 7 and 8, the former acting as a pressing-cylinder. The thread 6 produced by the roving is then passed under the needle 5 and attached to the spindle 4. Thereupon if the spindle be rotated rapidlyfor instance, at the rate of three thousand to four thousand revolutions per minutewhile the cylinders '7 and 8 are turning at a relatively slow rate-say eighty revolutions per minuteand assuming that the needle-box is made stationary, the torsion and winding of the thread 6 under tension on the spindle 4 will be effected as follows: The thread 6 carried along by the spindle a will also carry along the needle 5 and will cause it to describe a circle around the spindle at the same time as the thread is subjected to torsional action. On the other hand, when the length of the thread increases between the spindle and the cylinders the needle will remain be- Serial No. 23,635. (No model.)

hindthat is to say, will turn less quickly owing to this extension of its length and in consequence of its inertia and the centrifugal force which is acting on it. The result is that the thread 6 is wound on the spindle at the same rate. as it is given off from the cylinders at a tension which may be expressed by the weight of the needle augmented by the centrifugal force. In reality the needle-box is actuated by an irregular or regular alternating upward-and-downward motion in such a manner as to carry the thread onto the spindle, so as to form cop or bobbin.

In the accompanying drawings some forms of the boXes with a needle or with needles are represented by way of example. I

Fi l is a general view of the arrangement. Fig. 2 represents some needle-boxes arranged on the frame of the machine, partially shown. Figs. 3, 4, and 5 are vertical sections and a plan, respectively, of the needle-box represented in accordance with the first of the forms. Figs. 6, 7, and S are similar views of the needle-box according to the second form.

Figs. 9, 9, and so on to 93 represent different forms of needles. Figs. 10 and 11 are vertical sections of the needle-box, showing different regulating arrangements.

In Fig. 2 the ring-frame of the spinning frame is shown partially in elevation and carries two needleb0xes fixed by means of screws l1 and pressing-screws 15, the latter preventing the boxes from turning or being raised. The needle-boxes are illustrated in detail in Figs. 3, 4, and 5 and are each formed of a bottom 1 and a cover 2, prevented from turn.- ing by a headed bolt 11; the cwer 2 are both provided with a central opening 3, through which the spindle 4 passes, and a hollow space 13 is arranged between the bottom and the cover in order to enable the needle 5 to move freely on the upper surface cleft, and, further, a slight incline 17 is formed on a suitable side of the cleft in order to avoid The bottom 1 and vibrations of the needle when the latter glides with this kind of box the interior circle of the in front of the cleft. The needle represented as 5, Figs. 3 and 5, is simply rounded off at its ends, so that it may slide easily in front of the cleft 1 1 and may be kept straight. The needle is in equilibrium while winding upon the small diameter of the cop, because while it revolves about the spindle e the thread eon tacts exactly with its middle, as shown in Fig. 1, so that at each side of the said point of contact there is an equal length of needle, and hence an equal weight, thus avoiding any tendency of the needle to bind in the spinningring. In proportion as the winding takes place on a large or small cop or bobbin diameter the needle recedes from or approaches the spindle.

The needle, formed as a hook 1S, (represented in Fig. 4 may be employed for spinning high-number threads only when a rather heavy and strong steel needle is required. This needle is also balanced and may be set to work in the same boxes as the preceding one. Its ends are rounded off, so that it may slide easily in front of the cleft and that it may be kept straight. The long hook with which it is provided in the middle extends beyond the upper surface of the cover 2 and serves for hooking the thread without its being necessary for the latter to pass through the cleft 1a. In order to introduce the needle into the box,

the cover 2 is removed and is replaced again after the needle has been put onto the base or bottom 1.

For the purpose of passing the thread un der the needle 5 without removing the cover 2 when, for example, the said thread is broken in the course of the work, the spindle 4 is stopped by means of a brake, a small quantity of the thread is unwound from the cop or bobbin, and the thread introduced into the cleft Ll until it comes below the level of the needle. The needle is then slid with the finger on the thread in front of the cleft into the position indicated by dots in Fig. 5 and the thread drawn out of the cleft. It is evident that for the passage of the thread the cleft 1% must always correspond with that in the cover.

The needle box illustrated in Figs. 6, 7, and S differs from the preceding one in this, that the cover is cut out, as shown in those figures, in order to allow the ends of the fingers to reach the extremities of the needles when it is necessary that they should be moved. In this kind of box the cleft 14 of the cover is formed in one of the arms or branches supporting the interior circle of the cover, and it has the form previously indicated. Moreover, the distance between the bottom 1 and cover 2 must be capable of being regulated as desired accordingly as the number of thread requires a light thin needle or a heavy thick needle. This distance may be roughly regulated by means of spare disks 20, more or less thick, which are inserted between the ring-frame 10 and the bottom 1 of the box. It should further be remarked that cover is provided with a shoulder or ledge 21, the object of which is to prevent the bent extremities of the needle from taking hold of the arms or branches 19. In order that it may not be necessary to change the disks 20 for each number of needles, the latter may be made heavier by lengthening them. Different forms of these needles, either straight or hooked, with a single or double eyelet or loop at their ends, turned up or not, &c., are shown in Figs. 9, 9, and so on to 9 These needles are made of steel wire or any other suitable material.

The cover-piece 2 may be effectively regulated, as shown in Fig. 10, by means of a spiral groove formed in a piece 22, arranged beneath the bottom 1 and retained by the bolt 15, which engages in the spiral In turning the piece 22 to the right or left it is raised or lowered and the piece 1 is brought nearer to or removed farther from the piece 2.

Fig. 11 shows a needle-box into which the needle can be introduced without the neces sity of removing the cover 2. For this purpose a small hole 245 is formed in the side of the cover 2 in such a manner that when the piece 1 is lowered, as shown in Fig. 11, the needle may be put in onto the bottom of the same through the opening The piece 1 is then raised again until its upper surface reaches the normal level, (indicated by dots,) and thus closes the opening 24, so as to prevent the needle from coming out of the box. The hole 21 may be employed, as is obvious, in all the arrangements described above for regulating the bottom 1.

The needle-frames or needle-boxes above described may be employed for spinning cotton, wool, or any other textile material, and the dimensions of the boxes vary according to the material to be spun, but the principle of the invention always remains the same.

The technical results obtained with the above-described needle-box are as follows: The employment of fine strong needles enables the spinning to be carried on at a great rate and the thread obtained is very round and glossy; further, by employing suitable needles the tension of the thread may be regulated while the thread is being wound around the spindle.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- 1. In a device of the character described, a spinning-ring having an annular groove in the wall of its bore, and a slot extending from the upper face of the spinning-ring downwardly to said groove.
